While buying on Iconfinder or being charged for the renewal of your Pro subscription, some payments may be unsuccessful. If this happens, Iconfinder will return an error code that informs you what the problem with your credit card might be. Please visit the article on Reasons why credit card payments fail for more information. 

For subscriptions, Iconfinder will retry the charge a few times during 30 days. If we don't succeed at renewing your subscription, it will become paused. Read more about Paused subscription and about our Policy for unpaid subscription periods.

If you are trying to buy icons, this means that you have entered your credit card number incorrectly. If this is an automatic payment for a Pro subscription, then it means that the card details you have saved on your Iconfinder account are no longer correct. This can happen if your card details have been updated by your bank after you have added the card to Iconfinder, which caused for the card on Iconfinder to have an incorrect number. 

Solution: Please update your card details on Iconfinder by going to Payment settings. Contact customer support if you want to use another payment method.
